Hydraulic deadweight tester (DWT) uses calibrated weights to apply precise pressures to test devices, calibrating pressure measuring tools. These systems are like the backbone of many industrial operations, powering everything from heavy machinery to precision tools. From the automobile and oil manufacturing industries to aeronautics, the food industry, and the chemical industry, the application of hydraulic deadweight testers in Singapore is vast.Ā
However, like any complex system, these instruments require regular maintenance to maintain top-notch performance and longevity.
In this article, weāll discuss a maintenance checklist guided by our experts:
- The first step is to regularly check hydraulic oil levels and quality as specified by the manufacturer. Depending on the instruction, itās recommended to change the oil every 2,000ā3,000 hours of operation. Also, try to keep entry points clear of debris to minimise contamination risk.
- Replacing hydraulic filters regularly to prevent clogs and maintain system efficiency. Cleaning filter bowls is necessary for proper filtration.
- Inspecting hydraulic rods for wear, corrosion, and pitting, which can lead to moisture accumulation and system problems. Reach out to professionals for proper measurements.Ā
- Working with a hydraulic deadweight tester in Singapore, organisations must check the seals regularly. Damaged seals can lead to leaks and equipment hazards. Monitor seals for signs of wear and replace them as needed to maintain system integrity.
- Inspect hydraulic lines for signs of damage, including fluctuations in pressure and line thickness. Address any issues to prevent equipment damage and leaks.
- Maintain optimal fluid levels to prevent damage to pumps and ensure proper system function. Follow manufacturer specifications and avoid mixing oils.
- Keep breathers clean and inspect them regularly for damage. Replace filters and caps as needed to prevent contamination.
- Check hoses for damage or wear that could restrict fluid flow or cause leaks. Look into the pipes and fittings for dents or corrosion.Ā
- Monitor for signs of leaks, including excessive oil consumption and overheating. Address leaks promptly to prevent safety hazards and environmental damage.
- Check the system temperature using thermometers and investigate any abnormalities promptly. High temperatures could indicate issues with coolers or relief valves.
- Check for aeration within the reservoir, which can cause overheating and component wear. Look for foaming or unusual noises as indicators of aeration.
- Perform visual and contamination tests on hydraulic fluid to assess its quality. Look for abnormalities in colour, odour, and viscosity.
- Monitor servo valves for temperature abnormalities and erratic operation, which could indicate contaminated fluid. Address issues promptly to ensure proper valve function.
- Use an infrared thermometer to identify areas of high heat on electric drive motors. Service overheating components to prevent further damage.
